Using lithic assemblage formation to approach Middle Palaeolithic settlement dynamics: El Salt Stratigraphic Unit X (Alicante,Spain)

The superposition of anthropogenic remains usually results in archaeological palimpsests, hindering an accurate characterization of the behavior underlying such remains. Aimed at facing this methodological constraint in the study of Palaeolithic contexts, we present a contextual approach to Neanderthal settlement dynamics based on an understanding of lithic assemblage formation processes. We focused on a set of lithic artifacts from the Middle Palaeolithic site of El Salt. With the goal of isolating temporally constrained units of behavioral analysis, we analyzed the spatial distribution of lithic, faunal and combustion remains. Then, the lithic records from each of the resulting units were analyzed from a genetic and technical perspective. This goal was achieved by identifying lithic Raw Material Units (RMU) through observations on reduction processes, refits and their spatial distribution. Our results suggest that El Salt SU X lithic remains represent several diachronic human occupation episodes and different site functions. This study illustrates the benefit of investigating lithic assemblage formation processes to alleviate the palimpsest problem in Palaeolithic contexts.     

Milky Quartz Bipolar Reduction and Lithic Miniaturization: Experimental Results and Archaeological Implications

We present experimental data examining the energetics and identification of axial bipolar reduction in contexts of lithic miniaturization on milky quartz. These experiments answer two specific questions. First, does bipolar reduction provide any benefits over freehand reduction? Second, can axial bipolar reduction be distinguished from freehand reduction? Our data show that bipolar reduction requires significantly less time to reduce a percentage unit of core mass and to produce a millimeter of cutting edge on milky quartz than freehand reduction. Milky quartz bipolar reduction surpasses even the cutting edge production efficiency of obsidian pressure blades. We outline a series of quantitative criteria for identifying bipolar cores and flakes. Our results show that bipolar cores and flakes can be distinguished from those produced using freehand reduction by quantifying platform crushing, distal flake rebound scars, bulb shearing, as well as axial, bipolar, and splintered flake terminations. Our results challenge the widely held perceptions about the wastefulness of bipolar reduction and provide clear guidelines for identifying this reduction strategy in archaeological milky quartz assemblages.     

Use of robust methods to determine quadratic surfaces: application to heritage

3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).     

Archaeology on both sides of the iron bars

La conmemoración anual de la llegada de Colón a América como se experimenta en Argentina proporciona un foco para la definición de preguntas acerca de la comprensión de la arqueología como conocimiento. Para los grupos Indígenas es el aniversario del último día de la independencia de las poblaciones aborígenes. Los arqueólogos deben cuestionarse su posición cuando estudian el mundo y los objetos indígenas. Las interpretaciones de los “pioneros” arqueólogos argentinos son discutidas junto con el concepto de “la ruptura metafísica” sobre la que la arqueología construye su objeto, esa ruptura entre el mundo indígena subjetive y el mundo del conocimiento arqueológico. En el siglo XXI quedan preguntas pendientes acerca de la arqueología que, si es vista como una práctica descolonizadora, debe implicar su propio proceso de descolonización. Proporciona la Arqueología de Un Mundo el contexto para continuar esta tarea descolonizadora?

Résumé La commémoration annuelle de l'arrivé de Christophe Colomb en Amérique, comme c'est le cas en Argentine, donne l'occasion de se concentrer sur des questions de définition concernant la compréhension de l'archéologie comme source de connaissance. Pour les groupes autochtones, cette journée est la dernière de leur indépendance. Les archéologues devraient se demander comment ils se positionnent quand ils étudient le monde et les objets autochtones. Les interprétations des “pionniers” argentins de l'archéologie sont discutées en lien avec le concept de “d'écart métaphysique” sur lequel l'archéologie construit son objet: cet espace entre la réalité du monde des autochtones et des archéologues qui revendiquent la connaissance à travers la méthode scientifique. Au 21ième siècle, il y a encore des questions à demander concernant l'archéologie, qui même si elle est per?ue comme une pratique décolonisatrice, doit inclure le processus de décolonisation d'elle-même. One World Archaeology procure une contexte pour continuer cette tache de décolonisation?

     

An Exceptional Response? Security,Development and Civil Society in Spanish Policy after 11‐M

This article considers the ways in which Spanish state institutions responded to the Madrid bombings of 11 March 2004 in the context of the global ‘War on Terror’. It examines three inter‐related arenas of Spanish policy after 9/11 in which security and civil society are invoked in ways that impact upon the country's development agenda toward its southern Mediterranean partners. The first relates to Spain's external relations with its North African neighbours, and in particular the place of migration in shaping these relations over the last decade. The second concerns Spain's political relations with the representative organizations of its own Muslim populations. A third area of analysis pertains to the juridical‐institutional reactions of the state to the 11 March attacks: how have public authorities and civil society been affected and refashioned in the face of jihadist terrorism on the peninsula? The author argues that in each of these domains, the post‐9/11 context generally, and the 11 March attacks in particular, have elicited a securitization of civil society, which has in turn been associated with the country's international relations and domestic politics. Such securitization, however, has only been partially successful, thus vindicating the continuation of ‘politics as usual’ among Spain's state officials and its civil society.     

THE EFFECTS OF ZONING IN SPATIAL COMPETITION

ABSTRACT This paper considers a location model to illustrate the effect of zoning on competition. A planner is in charge of designing a city in a circular space where firms and consumers are located on different sides. With this type of market configuration, equilibrium in location under concave transport costs is proved. Then, a welfare function with different weights attached to consumer and firm surpluses is introduced to highlight zoning regulation as an influential competition policy tool. Depending on the regulator's political profiles and the demand, it is shown that zoning can lead to strong, weak, or moderate competition.     

Sourcing ceramics with portable XRF spectrometers? A comparison with INAA using Mimbres pottery from the American Southwest

Seventy-five intact Mimbres and Jornada pottery sherds from the American Southwest were analyzed by portable XRF and instrumental neutron activation analysis (INAA). Examination of the data demonstrates that INAA and portable XRF results for elements common to both analyses can be used to construct similar compositional groups. When individual compositional groups are compared to one another, it is apparent that unambiguous separation of compositional groups is challenging by portable XRF given (1) the limited number of key discriminating elements that can be measured relative to INAA, and (2) the relative analytical precision and accuracy of portable XRF for measurements of intact heterogeneous ceramics. We conclude that sourcing intact ceramics by portable XRF is challenging and that bulk analytical measurements, such as INAA, remain a better approach for sourcing archaeological pottery.
